Default P0193 code plus amber engine light

I have a P0193 code plus amber engine light, prior to this I was starting to see occasional hesitation on acceleration.

Research seems to indicate the most likely cause to be faulty Fuel Rail Pressure Sensor although it could be electrical related, I decided I would first try changing it out before taking on electrical diagnostics.

Here are the codes I got:



So then the fun started, I located the fuel rail pressure sensor in the car and it quickly became apparent that it is not easy to access:

I moved a large hose out of the way and then tried to remove the next one but don't know how to release the clamp without damaging (see below circled in yellow)
Also am I in for any surprises or do you have helpful hints if I get past this?


Thank you for your time

Gave it another try without success though I didn't try too hard because the more I look the more it looks like I need to remove a bunch of stuff to get to it. Is there some kind of workshop manual that tells you what steps are required or has anybody done this before that would be willing to share steps?

Main page in the "stickies" is a downloadable workshop manual.

OK thanks, that confirmed what I suspected, I will need to remove the throttle body to get to it, rather annoying since I changed that a couple of years ago, oh well might be easier this time!

So quick update, I replaced the Fuel Rail Pressure Sensor, then cleared the codes and so far everything seems good, the codes have not returned. It is not easy to get to even after removing the throttle body but after after moving a few other things it's just possible.

This is the one I replaced it with if anybody needs to do this in future:
Standard Motor Products FPS17 Fuel Pressure Sensor Standard Motor Products FPS17 Fuel Pressure Sensor


Hope this helps somebody in the future.
